Transmission chattering after switching to motul gear300
 

Switched to motul gear 300 last week, everything is fine except there is a chattering noise when in neutral and clutch is not pressed. It had never happened before fluid change. I'm fine with the noise since it only occurs in neutral, just afraid that my transmission would be damaged. :sigh::sigh: Thank you for any input.

give the fluid time, it needs to 'break in' a little. Sounds weird, but the transmission will be much better.
